Abstract

The invention relates a compressed air recovery device, a compressed air supply system and a recovery module as well as to a method for operating a compressed air recovery device, to a control module and to a vehicle. A compressed air recovery device (30) comprises a compressed air inlet (1) to which a compressor (2) can be connected. The compressed air inlet (1) is connected to a pressure line (3) to which a system pressure line (5) is connected via a non-return valve (4). A drying unit (11) is arranged in the pressure line (3). A regeneration path (22) which can be connected to the system pressure line (5) depending on the switch position of a vent control valve (23) runs into the pressure line (3) between the drying unit (11) and the non-return valve (4). The supply of compressed air to the compressed air inlet (1) can be controlled by an electrically actuated supply control valve (17). In order to allow a varied and effective compressed air recovery at low cost, the throughput of compressed air through the regeneration path (22) is linked to the position of both the supply control valve (17) and the vent control valve (23).
